Does raising the supply voltage actually buy real gains in acceleration and speed? That is the question this project tackles. Kapman's Basement Workshop modified a Voron printer specifically to test what 24V, 36V, 48V and 60V do to motion performance, and running the whole ladder on one machine is in my view what makes the comparison worth following.
The build touched both hardware and software. The electronics pair a BTT Kraken MCU with Kraken LDO Devil Design stepper motors, a combination that seems well suited to pushing steppers harder. On the software side, the maker used Klipper TMC AutoTune to tune the stepper motors and worked from the printer.cfg file in the GitHub repository. That config being available in a repository is handy for anyone wanting to repeat the setup.
The purpose was to show what the higher voltages do to acceleration and speed, and the sweep covers four voltage levels in total. There is also a demo segment with an FLSUN delta moving its toolhead, its display reading speeds up to 1200 mm/s, with the nozzle set to 200°C and the bed sitting between 31°C and 41°C.
One thing stays open for me: the FLSUN delta is a different machine from the modified Voron, and how the two relate is never spelled out. It would help to know which readings belong to which printer before drawing conclusions about the 60V end of the sweep.
